Does anyone have a suggestion for either a temporary or permanent solution to the problem of rusted out engine pipes? One of mine has developed a hole about 100mm out from the head where the pipe begins to curve down. I looked at a few second hand ones today and they had all rusted out in the same spot. The mufflers are still good and I hoped I would be able to just weld on a new engine pipe. Are automotive exhaust workshops able to bend a new pipe to match the original?
The local exhaust workshop wasn't able to help. Part of the problem was that they are set up to handle pipe over an inch and a half. The engine pipe on the CB25RS is about inch and a quarter. I couldn't find anything on ebay. Any other suggestions? Given the number of rusted out engine pipes I have seen lately, someone else must have faced (and hopefully solved) this problem.
how about a Japanese aftermarket system http://global.rakuten.com/en/store/z-father/item/10002192/ But you have to loose the center stand
Take it to a welder. I had a lot of cancer in a SRX250 system and a welder fixed it. I just wanted it sealed for paint. He made it like new! He cut equal diameter pipe and dropped it in a bit at a time in semi circular pieces. After tacking and final weld, he smoothed it all out with different grades of grinding pad. It was worth every cent.
How did you go with eBay? I'm looking for a right muffler for my second CB250RS... Sent from my SM-G935F using Tapatalk
I didn't find anything suitable on ebay. The Japanese aftermarket one looks interesting, but I am keen to keep the original look and don't want to lose the centre stand. I haven't completely given up on motorcycle wreckers yet. However, I think what I will eventually have to do is buy a couple of mandrel bends and replace the affected top section of pipe. The muffler and the bottom half of the pipe seem to be OK. The top bend appears to be about 125 degrees and a couple of mandrel bends from somewhere like this should be a fairly neat, cheap solution. http://stores.ebay.com.au/ecsengine...06495018&_sid=863425598&_trksid=p4634.c0.m322 If I can get a neat enough weld and paint the pipe flat black it should look OK. In the meantime, I stuck a bit of JB Weld epoxy in the hole and it is still there about 500km later, including a trip of 400km in one day. I thought it would have fallen out as soon as the pipe got hot. Maybe it doesn't soften as much with heat as normal epoxy resin.
I obtained my cb250rsa with an aftermarket 2 into 1 and did not like it at all I then purchased a set of down pipes from a uk dealer and some general purpose reverse cone megaphones from a company call bsa A11 in the Uk then purchased some steel pipe and a migwelder Made up cardboard models and then cut my pipe and then fabricated adapters to get it all into place the header pipes are lovely chrome as are the silencers but the adapters are painted black then made up the support brackets took it for an MOT failed for to much noise second attempt took off the reverse cones fabricated a flat plate and the the silencer was perforated through the plate with two 16 mm dia pipes noise level much reduced however it does not rev as well as with the reverse cones but the bike is still fast enough for me with the reverse cones it would go into the red in all gears I will try and get some pictures on line within a few days Love the bike and only yesterday had a superb ride of 100 km with no problems whatsoever You have to love fettling as well as riding when working on these classics Trev
I have to say @Frankster that that is the FIRST SRX250 I have seen in Matte Black that looks good. Probably because of the accents being the frame, wheels etc but very nice I still wouldnt do it though
Thanks Andy. Matt black is kinda my thing, but I'm seeing a professional about it and hopefully, in good time, I will be cured.
Just come in from a 20 mile ride on the Honda and I love it Getting back to the exhaust the adaptors were made up of 32 mm dia mild steel pipe and go from the headers to the new silencer these were then painted black and as they are tucked away it does not seam to bad I would have preferred the real things but gave up after trying almost everywhere for the last 12 months Thanks moderators for tidying up the pictures not used to new fangled systems Regards Trev
I have a freshly rechromed right hand exhaust in good condition, the chromer saw fit to drill a hole in it so that the fluid would escape however, this cant be seen once fitted. I got a pair made for mine by Peter Weller http://www.pgwengineeringtorbay.co.uk/ fantastic job they look as good as the original and he made them from Stainless Steel
